"I hope so," said Jones when quizzed about whether he will be back for the sequel. "I'm not sure the script is totally sorted out yet, but I'm waiting to hear about that."

Chris Evans, Sebastian Stan and Samuel L Jackson are among the actors reprising their Captain America roles for the follow-up, while Anthony Mackie will debut as the Falcon and Frank Grillo as the villainous Crossbones.

Jessica Brown Findlay (Downton Abbey), Emilia Clarke (Game of Thrones), Teresa Palmer (I am Number Four), Imogen Poots (Fright Night) and Alison Brie (The Five-Year Engagement) are all said to be in the running for a new female lead.

The Anthony and Joe Russo-directed Captain America: The Winter Soldier will be released on April 4, 2014.
